Also, pipes leading out from each end of the reservoir into the room. Also, a pipe from the top of thereservoir, leading toa chamber above, and thus purified air is discharged at either end of the stove, or at the bottom, or conducted to a chamber above, directly fi'om the reservoir or hot-air chamber.
